Answer:
Option B,D and E will create dilation.
Step-by-step explanation:
Dilation is the enlarging or shrinking of an element using a common scale factor.
If the same factor is multiplied by the elements, the dilation is created.
Looking at the options:
Option A
O (x,y) -----> (2x,4y)
if we take 2 as common we get 2 (x,2y) not the original coordinates (x,y). So, no dilation.
Option B
O (x,y) -----> (-2x,-2y)
if we take -2 as common we get -2(x,y) which is same as original coordinates. It would create dilation.
Option C
O (x,y) -----> (92x,2y)
if we take 2 as common we get (46x,y) not the original coordinates (x,y). So, no dilation.
Option D
O (x,y) -----> (3x,3y)
if we take 3 as common we get 3(x,y) which is same as original coordinates. It would create dilation.
Option E
O (x,y) -----> (1.2x,1.2y)
if we take 1.2 as common we get 1.2(x,y) which is same as original coordinates. It would create dilation.
So, Option B,D and E will create dilation.

The manager of the zoo where the ticket price for an adult is $9.50 and the ticket price for a child is $6.50 wants to make at least $800 on a Saturday. Let x be the number of adult tickets and y be the number of child tickets
Answers
Complete Question
The manager of the zoo where the ticket price for an adult is $9.50 and the ticket price for a child is $6.50 wants to make at least $800 on a Saturday. Let x be the number of adult tickets and y be the number of child tickets. Choose the inequality that shows the numbers of tickets that need
A) 9.50x + 6.50y ≥ 800
B) 9.50x + 6.50y < 800
C) 9.50x + 6.50y > 800
D) 9.50x + 6.50y ≤ 800
Answer:
A) 9.50x + 6.50y ≥ 800
Step-by-step explanation:
Let x be the number of adult tickets and y be the number of child tickets
We are told that the zoo wants to make at least $800, this means greater than or equal to $800
Therefore, inequality equation is given as:
$9.50 × x + $6.50 × y ≥ 800
= 9.50x + 6.50y ≥ 800
Therefore option A) 9.50x + 6.50y ≥ 800 is correct.

This is a reflection over the x-axis so its only the y-intercept that changes.
Answer:
its a reflection
Step-by-step explanation:
If it were a rotation, it wouldnt have overlapped.
If it were a translation, It would have been the wrong way up and not overlapping.
When reflected over line x, it will overlap because it stays rigid and does not change shape or size.

For each situation, write an expression answering the question. The expression should only
use multiplication,
a. A person's salary is $2,500 per month. She receives a 10% raise. What is her new salary,
in dollars per month?
b. A test had 40 questions. A student answered 85% of the questions correctly. How many
questions did the student answer correctly?
C. A telephone cost $250. The sales tax is 7.5%. What was the cost of the telephone
including sales tax?
Answers
Answer:
The expressions for each statement are as follows:
a: 2500+(0.10*2500)
b: 40 * 0.85
c: 250 + (0.075*250)
Step-by-step explanation:
Part a:
Given
Salary = $2500
Percentage of raise = 10%
The new salary will be:
[tex]= 2500+ (10\%\ of\ 2500)\\=2500 + (0.10*2500)\\=2500+250\\=\$ 2750[/tex]
Part b:
Given
Total questions = 40
Percentage of correct answers = 85%
The required expression for correct answers is:
[tex]= 85\%\ of\ 40\\= 0.85*40\\=34[/tex]
Part c:
Given
Price of phone = $250
Percentage of sales tax = 7.5%
The required expression is:
[tex]Cost\ with\ sales\ tax = 250 + (7.5\%\ of\ 250) \\= 250 + (0.075*250)\\=250+18.75\\=268.75[/tex]
Hence,
The expressions for each statement are as follows:
a: 2500+(0.10*2500)
b: 40 * 0.85
c: 250 + (0.075*250)

Colin buys a tv for £780.
It depreciates at a rate of 5% per year.
How much will it be worth in 6 years?
Give your answer to the nearest penny where appropriate.
Answers
Answer:
£573.40
Step-by-step explanation:
Amount = cost price - total depreciation
depreciation (1st year ) = 5% of £780
= [tex]\frac{5}{100}[/tex] x 780
= 0.05 x 780
= £39.00
depreciation (2nd year) = 5% of £741
= £37.05
depreciation (3rd year) = 5% of 703.95
= £35.1975
depreciation (4th year) = 5% of 668.7525
= £33.437625
depreciation (5th year) = 5% of 635.314875
= £31.76574375
depreciation (6th year) = 5% of 603.5491313
= £30.17745656
Total depreciation = £39.00 + £37.05 + £35.1975 + £33.437625 + £31.76574375 + £30.17745656
= £206.6283253
Total depreciation = £206.6283253
Therefore,
Amount after 6 years = £780 - £206.6283253
= £573.3716747
= £573.40
The worth of the TV after 6 years is £573.40.

Cesar, Carmen, and Dalila raised $95.34 for their tennis team. Carmen raised $12.12 less than Cesar, and Cesar raised $35 more than Dalila.
If x = the amount raised by Carmen, choose the expressions that represent the amount each other player raised.
Answers
Let Cesar's, Carmen's and Dalila's amount be represented by x, y and z respectfully.
Since they're money sum up to $95.34, the first expression will be;
x+y+z=95.34
Carmen_y_ is $12.12 less than cesar_x, so the equation will be ;
y=x-12.12
Cesar_x_raised $35more than Dalila_z. So the equation will be;
x=z+35
making z the subject, z=x-35 .
Substituting the Second equation into the first one, we get;
x+x-12.12+z=95.34
Subtracting the third equation into the new equation we get;
x+x-12.12+x-35=95.34
Simplifying, we get 3x- 47.12= 95.34.
3x=142.46

Answers
Answer:
3,4,5
Step-by-step explanation:
Here, we want to select the set that could work and the sides of a right angled triangle
the correct answer is 3,4,5
These set are called a Pythagorean triple
This is because adding the square of the two smaller number will give the square of the largest number
What we are saying here is that by adding the square of 3 and 4, we get the square of 5 which illustrates that Pythagoras theorem works for the set
